Karim Benzema scored an extra-time penalty as Real Madrid pulled off another astonishing comeback in the Champions League to stun Manchester City 3-1 on Wednesday and book a showdown with Liverpool in the final. City looked certain to go through when Riyad Mahrez put them 1-0 up and 5-3 ahead on aggregate but Rodrygo, on as a substitute, scored an incredible late double, his goals in the 90th and 91st minutes sending the tie to extra time.
